做项目时，涉及到多个异构系统的交互，采用了Apache CXF,下面通过实例演示Apache CXF 2.7与Spring集成，发布和调用Web Service。

环境：

win8 64位

tomcat 7 64位

jdk 7 64位

cxf 2.7

spring 3

项目结构

1、在同一个项目中模仿服务端和客户端（实际项目中是不可能的，但是客户端却依赖于服务端的Web Service接口，那么可以通过导出jar的方式）

类库

在apache cxf 官网下载cxf2.7,解压，在lib下即可找到这些jar

几个类的代码

package com.test.server;

import javax.jws.WebService;


@WebService
public interface IHelloWorldServer {
	public String sayHello(String username);
}

package com.test.server;

import javax.jws.WebService;

@WebService(endpointInterface = "com.test.server.IHelloWorldServer", serviceName = "HelloService")
public class HelloWorldServerImp implements IHelloWorldServer{

	@Override
	public String sayHello(String username) {
		
		return username+" : HelloWorld";
	}
	
}

package com.test.client;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.test.server.IHelloWorldServer;

public class HelloWorldClient {
	public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-client.xml");
        IHelloWorldServer helloService = (IHelloWorldServer) context.getBean("client");
        String response = helloService.sayHello("jialin");
        System.out.println(response);
    }

}

相应的配置文件

        <property name="serviceClass" value="com.test.server.IHelloWorldServer" />
        <property name="address" value="http://localhost:8080/cxf_demo/ws/helloService" />
    </bean>
</beans>

web.xml

<?xml version="1.0" encoding="UTF-8"?>

配置完成后，部署到tomcat，成功启动后。

在浏览器中输入

http://localhost:8080/cxf_demo/ws

说明web service发布成功，可以点击进入查看相应的WSDL.

这时运行客户端得到如下结果

以上是在同一个项目中模仿客户端和服务端。下面再看一个服务和客户端不在同一个项目中的，这是符合现实的。

2、

服务端

与上述项目结构一样，只是没有com.test.client这个包和applicationContext-client.xml

客户端

新建一个普通的java项目即可，项目结构：

注意cxf-serverinterface这个jar，是到处的服务端的接口即为com.test.server.IHelloWorld

HelloWorldClient.java

package com.test.client;


import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;


import com.test.server.IHelloWorldServer;


public class HelloWorldClient {
	public static void main(String[] args) {
        ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-client.xml");
        IHelloWorldServer helloService = (IHelloWorldServer) context.getBean("client");
        String response = helloService.sayHello("jialin");
        System.out.println(response);
    }


}

applicationContext-client.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:jaxws="http://cxf.apache.org/jaxws"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
                       http://www.springframework.org/schema/beans/spring-beans.xsd
                       http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
    <!-- 
        ***注意*** 
        手动添加的内容：
        xmlns:jaxws="http://cxf.apache.org/jaxws"
        http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"
     -->
    
    <import resource="classpath:META-INF/cxf/cxf.xml" />
    <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
    <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />

    <bean id="client" class="com.test.server.IHelloWorldServer" factory-bean="clientFactory" factory-method="create" />

    <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
        <property name="serviceClass" value="com.test.server.IHelloWorldServer" />
        <property name="address" value="http://localhost:8080/cxf_demo/ws/helloService" />
    </bean>
</beans>

测试：

部署服务端到tomcat，启动。

启动Web Service服务，然后访问http://localhost:8080/cxf_demo/ws地址来确定web service启动正确。

运行Client测试类，运行结果：
